  • My 9 year old nephews drawing of stars
    I think Celestia could be a good one. I also thought about SpaceEngine, but AFAIK it was kind of terrible at generating realistic planetary systems, among other things (pricey, huge, etc.). Source: over 1 year ago
  • What are the best resources to explore space from my computer?
    Celestia was something I played with before. Pretty interesting. Source: over 1 year ago
  • Lunar Occultation of Mars
    Celestia looks as though it would do it. Source: over 1 year ago
  • Tips to visualize Apollo 17 trajectory
    I'm looking for data and software to visualize the Apollo 17 trajectory (especially the "powered descent", lunar rendezvous and entry). I'm thinking of using celestia. I'm look for a data tables as well (time stamp, position for each part of the stack). Any tips are appreciated. Source: over 1 year ago
  • Help rediscovering a certain night sky exploration program?
    Yes, that's Celestia most likely. I'm not sure it is still maintained though. Source: over 1 year ago

  • Unofficial "Space Support Group"
    How about spacetime.am? A website or tool for time differences and to manage stuff and be able to check stuff. Previously, I tried to make it easier to manage our time zones thingy but then I thought maybe it isn't good. So I looked up and found it. Here's the screenshot link and you can search it up yourself and maybe someone, probably the creator of this maybe. Bye bye for now. Source: about 3 years ago
